July 2013 www.sname.org/sname/mt ( from the editorial board )Eagle-eyed readers of (mt) who follow such things will know that we originally had sched- uled marine and hydrokinetic (MHK) technologies for the October 2013 issue. en real life intervened in the form of schedules and workloads, which gave us the opportunity to move MHK up to this July issue. Im actually really pleased by this; theres a ton of innova- tive and exciting work being done in this space. We set up this issue, in a way, with an introduction to the MHK sector in our October 2012 issue, an excellent piece authored by Cardinal Engineerings Brian Lounsberry. Brian actually did too good a job on that one, as his was the rst door we knocked on when we began planning this MHK issue. As we talked about the work being done with various MHK technologies, Brian suggested we talk with his colleague Whitney Blanchard, an engineer at Cardinal who provides support to the United States Department of Energys Wind and Water Power Technologies Oce. With her work focusing on technology development of MHK energy systems, Whitney is well versed in whos doing what in this sector. She helped to connect us with device developers, designers, program managers, and other movers and shakers in the ocean renewable energy industry, and the result is the issue you hold in your hands. One of those key players was Jarlath McEntee at Ocean Renewable Power Company, who contributed an informative feature on his companys tidal energy system, which was the rst tidal energy project to deliver power to an electrical grid in North America. Another was Commander Rob Cohen, who checked in with a behind-the-scenes look at the work being done by the United States Navy on developing and testing wave energy converters. We also have a detailed exploration of a free-stream tidal turbine, the SeaGen, installed on the coast of Northern Ireland in 2008 and now producing energy as the tides rush in and out of Strangford Lough. e success of SeaGen, in fact, is serving as a model for other tidal energy projects in the United Kingdom and in Europe. eres much more on MHK developments in this issue. Many thanks to Whitney Blanchard and to the team at Cardinal and the Wind and Water Power Technologies Oce for their out- standing work. And take a look at the box below to see whats coming up in (mt) . As you already know, topics are subject to change, but were developing some very relevant and thought-provoking content to share with you in upcoming issues. Its going to be a great ride. Douglas R.
